摘要： A technique for enhancing the image quality in intravascular ultrasound imaging increases contrast between blood and vessel wall processes image data using a point-wise t-statistic technique. Data from an ultrasound transducer is digitized and stored in a memory buffer [500]. For each point in the image, a t-statistic value is derived from signal amplitude values for the same point at a sequence of previous frames [502]. An image is then generated and displayed using the t-statistic values for the intensity of each point [504]. The improvement in contrast ratio as compared to averaging techniques is most significant at highly oblique angles when contrast ratio is particularly poor in the unprocessed signal.

摘要： A variety of embodiments relate to systems, methods, circuits and devices are implemented to perform location-based correlations. One such embodiment relates to a circuit-implemented method for use with an actual probe within an anatomical structure. For a virtual probe at a virtual location within a model of the anatomical structure, virtual image data captured by the virtual probe is generated. The virtual image data is assessed through a probabilistic comparison of the virtual image data to actual image data captured by the actual probe at an actual location. Based upon the assessment, a correlation is updated between the actual location of the actual probe and a sensed location of the actual probe to provide synchronicity between the sensed location and actual location. For maintaining the synchronicity between a subsequently sensed location and subsequent actual location, the assessment is used to select a new virtual location for the virtual probe.

摘要： A method of posting ephemeral posts is disclosed. The method starts with receiving, from a user of a social network, a request to post an ephemeral post, the request including an ephemeral variable associated with a threshold event. The ephemeral post is posted on behalf of the user. Then an occurrence of the threshold event is monitored. When the threshold event has not occurred, the post is allowed to be accessible to at least one viewer other than the user. When the threshold event has occurred, the post is blocked from being accessible by the at least one view other than the user.

摘要： A computer-implemented method for generating a composer prompt to induce a user to post a message at a social network system is disclosed. The method starts with retrieving information about the user, the user information being stored in a profile at the social networking system. It assesses the user information and temporal information to determine content and format of the composer prompt. Then the method generates a new composer prompt based at least partially on an assessment of the information and display the new composer prompt to the user.
